As a better embodiment, as shown in FIG. 1, a blockchain-based anti-counterfeiting method includes the following steps:

Step S101: preset a commodity identifier, which is used as a data collector of the blockchain to record and monitor commodity information;

This technical solution provides an anti-counterfeiting method based on blockchain technology. It uses NFC chips or RFID to mark product information to ensure the authenticity of the information. It uses the blockchain data layer to store and encrypt luxury information to complete the blockchain. Data information storage. The P2P network layer implements decentralization. The data verification mechanism synchronizes information across the entire network. The PoW consensus mechanism determines which node obtains the block accounting right.

First, place a unique, independent NFC chip in each luxury product. For some products with low added value, you can use two-dimensional code or radio frequency identification RFID to mark them. These identification chips can be understood as the electronic "identity" of the product. Certification ", starting from the production and production of goods, each product goes through different channels, and the information formed will be different. The chip acts as a blockchain data collector and records all the goods' logistics, warehousing, and resale information. And monitoring to ensure the authenticity of luxury data information. .

In step S102, the commodity information is stored and encrypted at the data layer by using a blockchain;

The product information data identified by the NFC chip, RFID or two-dimensional code will be transmitted to the data layer of the blockchain. Including the circulation of luxury goods in the complete business cycle, such as the production process of luxury goods, logistics processes, and so on. Among them, the blockchain data layer encapsulates the block data structure and encrypted content. The block is composed of a block header and a block body. The block body includes all transaction information. The block header includes a hash value, a timestamp, and a Merkel tree root hash value. Among them, the timestamp records the block generation. Time, that is, transaction time, the Merkel tree enables fast verification of transactions. It is the only identifier for transactions in the block. At the same time, in terms of encryption, rely on digital signatures and asymmetric encryption algorithms to ensure data security. The data is encrypted and decrypted through public and private keys. Each chip has a private key. The private key can be viewed as the password of the chip. , The user must obtain the private key to have the right to view the chip information or modify the information, and the difficulty of cracking the private key password is quite complicated, requires supercomputing resources, and is almost impossible to achieve. Merkle Tree, also known as Hash Tree, is a tree that stores Hash values. The leaves of the Merkel tree are the hash values of data blocks (for example, files or collections of files), and the non-leaf nodes are the hash of its concatenated string of child nodes. Hash is a function that maps data of arbitrary length to fixed-length data.

In step S103, the interaction between nodes is realized through a blockchain network layer. The blockchain network layer includes a plurality of service nodes. Each service node interacts by sending messages, and the nodes and nodes are established at the blockchain network layer. The consensus mechanism between them provides decentralization for digital content interaction and provides guarantee for data point-to-point transmission verification;

Interaction between nodes is achieved through a blockchain network layer, which includes a plurality of service nodes, each service node interacts by sending messages, and establishes a node-to-node relationship at the blockchain network layer. The consensus mechanism provides decentralization for digital content interaction and provides guarantee for data point-to-point verification. First, the decentralization problem is solved through the P2P network. The network model is shown in Figure 2. The P2P network uses a flat topology. The status of each node is the same. Without a centralized server, each node participates equally. Functions such as checksum broadcasting are the basis of the decentralized network implemented in this application. Second, the network layer includes a data check mechanism. When a node receives a message from a neighboring node, it verifies the validity of the data. For valid information, this node broadcasts the information to the neighboring nodes. , To achieve the synchronization of the entire network message, and for invalid information, the node will not perform any forwarding operation. The function of immutable and traceable blockchain product information is realized through node verification.

Step S104: Promote each node to reach a consensus at the blockchain consensus layer through the proof-of-work mechanism, record all the on-chain data and keep all data states consistent. The proof-of-work mechanism is that when a node records data, The recorded data needs to be approved by most nodes in the blockchain before it can be recorded in each node of the blockchain;

Promote each node to reach consensus at the blockchain consensus layer through the proof-of-work mechanism, record all on-chain data and keep all data states consistent. The proof-of-work mechanism is the data recorded by a node when it records data Need to obtain the approval of most nodes in the blockchain in order to be recorded in each node of the blockchain. In a decentralized system, how to make nodes reach consensus is the key. This application uses a consensus mechanism based on proof-of-work PoW, so that a system with decentralized decision-making power can reach consensus. Each node solves a mathematical problem through the competition of computing power. The node that solves the problem the fastest will obtain the block accounting right (that is, the data information is written into the blockchain by the miner who has obtained the block accounting right), and The quickly resolved nodes broadcast across the network. Based on the consensus layer, brands or suppliers can write product information into the blockchain, and intermediate channels can write logistics information into the blockchain and monitor it in real time. The entire network is unified, the algorithm is simple, and it is easy to implement. Consensus can be reached by exchanging additional information, and disrupting the system requires significant costs.

PoW (Proof of Work), proof of work, Bitcoin uses the PoW mechanism in the block generation process. A qualified Block Hash consists of N leading zeros, and the number of zeros depends on the difficulty of the network. To get a reasonable Block and Hash, it takes a lot of calculations, and the calculation time depends on the speed of the machine's hash operation. When a node provides a reasonable Block and Hash value, it shows that the node has indeed undergone a large number of attempts to calculate. Of course, the absolute value of the number of calculations cannot be obtained, because finding a reasonable hash is a probability event. When a node has n% of the computing power of the entire network, the node has a probability of n / 100 to find Block Hash.

Step S105: Receive a commodity information viewing request sent by the user terminal, where the commodity information includes a commodity identifier of the commodity, and return the commodity information to the user terminal.

On the basis of ensuring that the luxury information is immutable and secure, consumers can directly view the information of each process node of the purchased product upstream through the smart terminal APP, learn the "history" of the product, and read the luxury product. Process information throughout the supply chain.

Step S202: The distributed ledger database encapsulates the blockchain data structure and encrypted content in the blockchain data layer. Each block of the blockchain includes a block header and a block body, and the block body includes all transaction information. The block header includes a hash value, a timestamp, and a Merkel tree root hash value, the timestamp records a block generation time, and the Merkel tree verifies a transaction;

Time, that is, transaction time, the Merkel tree enables fast verification of transactions. It is the only identifier for transactions in the block. Merkle Tree, also known as Hash Tree, is a tree that stores Hash values. The leaves of a Merkel tree are the Hash values of data blocks (for example, files or collections of files). Non-leaf nodes It is a hash of its corresponding child node concatenated string. Hash is a function that maps data of arbitrary length to fixed-length data.
